So that 'extra' registers (msp, psp, ...) are visible to user.

Added parameter to specify one stlink v2 of many

This adds a parameter to the function stlink_open_usb and to the binary
st-flash to specify one of multiple connected stlinks.
As the identifier the iSerial of the stlink is used.
If no serial is given the function and binary behave as before.

The controller doesn't clear them automatically when the operation
finishes, so to avoid getting errors we need to clear them manually
before we request another operation.

No loader yet, but we can erase!
